NEW LOOK QUESTION...
Jim,
My aircraft had a new look kit put on it in 1951. As you well know, that
closes in the area where the two rear windows were with metal and adds
the two "D" shaped Temco style windows. If I wanted to convert it back
to the old look, could I just remove that section and replace the windows
or is it more involved than that?

Bob,
It depends, are you talking keeping the flat shelf (uh, you do have the
flat shelf, right?) and putting the older style windows in? That can be
done. Or do you mean restoring to original? To do that, you need the slope
shelf parts and the 3 formed skins that go around the plexiglas. Those
skins are not as simple as they might appear, they have a formed edge
on them, recessed for the plexiglas. Also you need the retaining strips
for the outside of the 'glas. Sure it can be done, but its a fair amount
of work. -- Jim

LOSING SIDE WINDOWS IN
FLIGHT...
From: Jerry Swartz (JSw7211963@aol.com)
Subject: Re: N77759 Side Windows
Jim,
May or may not have told you, but did find some "Univair" sliding side
windows from Thomason Aircraft Products, with the original rubber framing
etc. When received, the original Plexiglas was evidently broken in transit,
so took them to my friend in the glass business, who replaced the Plexiglas
with Lexan. I've used Lexan before on other aircraft, but this is the
first in a Swift. I installed one yesterday, which took some tin snip
trimming to get it to fit, which is another story, but I found that there
sure is a difference between the Lexan window and the Plexiglas window
as far as stability is concerned. Lot's of flex in comparison. For instance,
with your hand on the center of the window, it will push in, or bend,
whereas the Plexiglas would not. I'm hoping that this is not going to
cause a problem in flight. Any experience with what I'm talking about??
-- Jerry Swartz

Jerry,
Yes, I have. I have lost several of those windows in flight. Others have
had them dent the horizontal stab or wing leading edges, but I've been
"lucky" and just lost the window. There are several negatives to using
Lexan, it can be "wavey" - somewhat akin to 'sheet" glass in a car as
opposed to "plate" glass. And of course, it is more flexible. It also
has some advantages. It's a lot stronger, and much easier to work with.
Does your glass fit very tightly? Otherwise it may depart the airplane
suddenly. Don't be alarmed if "poof" - it's gone! The rubber frames were
a little too flexible at first, after they got a few years old and hardened
a little they hardly ever were known to lose a window. As far as the FAA
goes, AC43.13-1A doesn't say you can't use it, only that ...materials
must be equal to its original or properly altered condition....well, is
the Lexan equal in this case?

You mentioned tin-snipping,
does that mean the frame? That's OK if you kept the sides parallel, the
window has to slide up and down freely, and not come out of the frame
at any point! Also, some Swifts do not have the slides perfectly parallel,
so the window will rock, but there isn't anything you can do about that.
If the slides (tracks, or whatever you want to call them) are not perfect,
that is a factory defect but it is a little late for warrantee work! Old
time Swift owners sometimes put an aluminum strip or a piece of safety
wire down the outside of the glass to act as a retainer. See why many
of those style windows were discarded? Regardless, I like them because
they are "factory". The rubber on mine is hard as rock and I don't think
I'm going to lose 'em. If your lexan is a little undersized you might
lose yours. You can push really hard on them and see if it's possible
to push them out. I lost one once pulling up into a loop and it departed
with a "bang" - my first thought was a wing had departed, but within a
millisecond I realized what had happened.

If you aren't happy with
the lexan, I suggest you bite the bullet, and replace it with plexiglas,
but you can lose plexiglas too! You can also "glue" the window into the
rubber - this has great potential for making a mess, and ruining the glass
but might work if you're careful. Maybe you could "lace" them in by drilling
holes and lacing them in with wire or cord. (no, I have not ever done
that, just a thought...) -- Jim

Jim,
Thanks for your input. The shop did use glue, at least that's what they
told me. The triming was done on the frame, in order to get it to slide.
It was about 1/4 " wider than the frame that I took out. The track down
in the sides of the fuselage must be larger, wider, or whatever, cuz the
window really drops down freely once it is clear of the frame around the
windshield. I guess, like you, I like the stock look well enough, that
I am going to at least try them and if all else fails, I can always put
the ones that came with the plane, back in. -- Jerry.

TEMCO STYLE "D" WINDOW
INSTALLATIONS...
Subject: Re: "D" Windows
From: Bud England <Dalswift1@aol.com>
From looking at the rubber trim, it looks like I should fit the rubber
around the glass, then put it in the window cutout. 'Course, I've never
been accused of being too smart. Missed you last week. It was probably
the best fly-in I've ever attended. -- Bud

Bud:
Yes, either way actually. Then there is a locking strip of rubber that
pulls in afterward - Mark (Holliday) has a tool that makes it easier.
A lot of commercial vehicles used such an arrangement back in the '40's
so you can still get that rubber (by the foot) at antique auto supply
places. Write Mark and ask him to describe or sketch the tool. -- Jim

OPEN SIDE WINDOWS IN
FLIGHT... (050500)
Subject: Re: OPENING OF SIDE WINDOWS IN FLIGHT
From: Gary Williams <garyjw@intekom.co.za>
Dear Jim, Can you please let me know what is the safe airspeed the
Swift is designed to fly with the side windows down. Can only one window
be opened at this safe airspeed, or must both be opened simultaneously.
Thank-you. Regards, Gary Williams - South Africa

Gary,
I don't know if there ever was anything published on this subject but
I can relate my own experience. One window down seems to operate fine
throughout the speed range. The first takeoff I tried one hot day with
both windows down scared the heck out of me when the tail shook after
lift off. I aborted the takeoff, thinking I had a real problem, like a
prop failure. I have since heard from others that they operate routinely
with both windows down with no problem. I have even seen a Swift operate
with the hatch removed with no problem, other than a slight buffeting.
I am leaving shortly for the annual Swift Fly-in in Athens, TN. -- Jim

"D" ADVICE ABOUT "D"
WINDOWS... (080300)
Subj: "D" Windows
From: Dalswift1@aol.com
Jim: I'm ready to put in my "D" windows, but I'm concerned about expansion
and contraction. It's really hot down here right now and I'm wondering
if the material expands and contracts enough to worry about. If cut to
length now, will it still be the right length this winter? Bud

Bud,
I presume you mean the length of the rubber strip that retains the window.
I would cut it just a little short in case it "grows" I have seen several
Temco's with a fairly wide gap where the rubber retainer butts up, and
that doesn't appear to hurt anything, although I have lost several in
flight, as have others! Most of the windows lost in flight were fairly
recent installations. If you put them in now, the rubber will take on
a "set" by the time you start flying it in a year or two. -- Jim

GOING BACK TO THE "OLD
LOOK"... (08400)
Subj: Original Globe Rear Windows
From: Bob Runge <ejectr@javanet.com>
Hi Jim:
Jim...... I'm talking with LP Aeroplastics about the rear windows. It
appears that the clear ones are .060" thick, but the blue tint ones that
are more original are made out of .125" stock. The spec on the .125" stock
could run min .085" - max. .155". I'm considering getting rid of the "new
look kit" and going to the old style windows. It appears that all they
did to my new look kit is rivet it right where the windows used to be
in the same original seat. I still have the original skins around the
window area and the slanted back shelf. Will the indent in the channel
where the original windows seat be deep enough for this type of thickness?

Bob,
The thicker plexiglas won't hurt a thing. If it does stick out a little
further, I doubt if you'll notice. I have a set of those windows over
at the hangar, I never realized they might be that thick. I will look
at them tomorrow and let you know how thick ours are. -- Jim

GOING BACK TO THE OLD
LOOK PART II... (080400)
Subj: Globe Rear Windows
From: Bob Runge <ejectr@javanet.com>
Hi Jim:
I have just finished pouring over my airframe logs with a fine tooth comb,
and cannot find any entry noting the installation of the new look kit
I have on my Swift. I believe it was installed during its conversion to
a GC1B from a 1A in 1951, although there is no mention of it being done
along with all the other listed work on the 337. I have also scrutinized
all the 337's and nothing there either. Must have been another case of
the vintage advantage and it just grew there.

Now my question. Rules and
regs say owners can replace side windows but not the windshields. I would
consider these rear windows "side windows". Left side and right side.
And the removal of the new look kit never happened because it was never
there according to the logs. And I am just returning something to its
original condition that was never changed from original in the first place.
In other words, can I remove the new look kit and put these windows in
myself? Thanks Jim. Best regards....... Bob Runge

Bob,
After reading some mail from you previously, I wonder, do you have the
"new look" installed? Do you still have the slope shelf? If you have the
"new look" kit you will have a flat shelf with a vertical bulkhead at
sta. 88.8. You might just have the "new look" style windows, not the whole
kit. Can you send me a picture? Just replacing the "new look" style windows
would be an owner permitted job. -- Jim

LOOK PART III: THE PLOT THICKENS... (080400)
Subj: Re: Globe Rear Windows
From: Bob Runge <ejectr@javanet.com>
Jim: Attached are 2 photos. I still have the sloped rear shelf. It appears
what I have in place of each acrylic original window is a metal replacement,
in the shape of the original windows, with "D" shapes cut in each side.
They are riveted in the original, indented channel seats, at each screw
hole that the acrylic windows would sit in and are riveted down the center
to the original window metal that would be there if the acrylic windows
were there. It meets the description of item 601 in A-766 Revision 12.

Bob,
You don't have a "new look". All you have are some new look style rear
windows. It should be fairly easy to reinstall the glass. Do you have
the retainer strips? -- Jim

No Jim, I don't. Some time ago Jim Thomason was kind enough to send me

like to have some originals if you know where I could get some, rather
than having to use my pattern to cut some out of .050" stock. You know......
one error compounded.

Bob,
Those strips are not exactly interchangeable from aircraft to aircraft.
But, if you don't mind some double holes, try for some used ones. They
are .050 and take a lot of an aluminum sheet! After reading the August
#4 GTS Newsletter I remembered something. I measured the thickness of
those Globe rear windows we have. They are about .100 thick. We got them
from LP last year and they are a light blue. -- Jim

I ordered a new windshield yesterday from Aircraft Windshield Co since
they are local and still have the active paperwork. There was some confusion
about the thickness when I placed the order. They said 1/8 (0.125), but
I recalled it was 0.150 or perhaps even 0.165 on the thickness. We agreed
on 0.150, but now I'm less certain. Instead of drilling a test hole in
the old one to measure, thought I'd ask you before they fabricate one
I won't like. -- Ron

Larry,
Most were .025. Some late ones used .032, so I suppose you could use either
of these gauges. After reading the August #4 GTS Newsletter I remembered
something. I measured the thickness of those Globe rear windows we have.
They are about .100 thick. We got them from LP last year and they are

Bob,
Well, I would rather use .125 than .062! .062 is just too thin (oh too
thin as they used to say in the airline biz whenever .020 and .025 aluminum
was used) The .125 should work just fine. -- Jim

THE BOAT BUNCH...(010401)Subject: "D" Window Rubber
From: Ed A. Lloyd <edlloydaustin@juno.com>
To: Bud England <Dalswift1@aol.com>
Hi Bud. I was looking through Denis last newsletter and saw your comments
about the rubber around the windows. I offer this for what it's worth.
I work in the boat business and on one of my trips to the Mastercraft
factory in Vonore, TN., not too far from Athens, I observed the following.
The rub rail they install around the perimeter of their boats was immersed
in a tub of HOT water and allowed to soak until it became very pliable.
Once removed from the hot water, the heavy plastic became super pliable
and was easily worked and bent to the contours desired. My bet is, this
procedure would work in putting the rubber around the windows in the Swift
also. The hotter the water the better. Use cotton gloves to handle the
"hot" rubber. Hope it works. Cheers......Ed Lloyd

RUBBER 'ROUND THE WINDOWS TRICK...(020101)Subj: Swift Window Rubber
From: Mike Pirowskin <SWIFT49@aol.com>
Hi Monty,
I enjoy and always learn something new reading your comments in the newsletter.
Thanks can never fully express the appreciation we all have for your willingness
to share your experience with the rest of us and your love of the Swift.
And now for the rubber around the window trick. First, I've never put
one in a Swift, but I did help some friends put rear windows in pickups.
We put the rubber on the window, then put soapy water in the groove that
goes into the frame. Next we ran a thin strong nylon line in the groove.
We got the window into position with part of the rubber in the frame.
Holding one side of the rope stationary, you push on the glass and at
the same time pull the other end at about 30 degrees to the window to
pull the lip of the rubber over the frame. The rope gives you leverage.
This is a two man job. If you think this would help anyone please pass
it along, otherwise, send it to the dumpster. Best regards. Mike, N2349B

Again i would like to thank u on the awesome service to all of the swifters

the "classic swift photos, from the Bill Larkins collection."
The "d" style window looks out of place. Did the man who owned
the swift in '55 install the "new look kit", then put a smaller
"d" window in? what's also strange is that it is a GC-1A with
a "d" window. was that done often? If u have time, please take
a look. I'm in no rush. swift flying, ---Austin Smith

Austin
That airplane did not have the "real" "new look kit"
in that photo. It had the old Globe slope shelf with some homemade rear
windows, patterned after the late Temco "D" windows. That was
quite a common mod back in the '50's. Back then, the "new look"
was the "in" thing. Today, I think the earlier Globe slope shelf
and blue back windows is more popular. Of course, many Swifts now have
bubble canopies. -- Jim

Subject: Blue Plexiglass
Regarding the blue rear window in Swift. Yes 2069 is the proper color
but it's not available in the proper thickness. The only thing you can
get is .125thk. The proper thickness is .090-.100. I've checked into it
and the only way .090 or .100 is available is to order an entire LOT of
4x8 sheets of plastic. Probably enough plexiglass to do rear windows for
the entire fleet. Anyway, I would buy 2 4x8 sheets. Is there anybody out
there, hopefully many, who is interested so we can get enough money together
to purchase a large quanity of the proper blue plexiglass. I've mentioned
it to the Swift parts dept. many times over the past 25 years as an item
that should be in stock. Interested parties contact porter.houston@comcast.net
and maybe we can get the stuff made. Porter

Jack
I think the original side plexiglas was .080. If you have something other
than the Temco rubber framed side windows you probably can use up to .125.
Since you are talking about drilling holes I would guess you have some
sort of modified frames. Why don't you just mike the broken glass and
replace it with the same thickness? A new AN bolt may help your wear situation,
check the existing pin or bolt for wear. It should mike .190. If the holes
are worn at the end of the actuating rod, steel washers can be welded
or brazed to the rod to restore it to new condition. -- Monty

MORE ON THE RTV CORROSION ISSUE...(090202)
Subj: RTV corrosion?
From: John Lindley <johnlindley@compuserve.com>
Here is what I remember about RTV and corrosion. Many years ago when the
Swift and I were young, I was working for an electronics company, and
we were using GE RTV to protect and seal the wires in the back of high
voltage connectors. We were told that the acetic acid in common RTV reacted
with the moisture in the air to cure the RTV. (Common RTV smells like
vinegar because acetic acid is the acid in vinegar.) When the common RTV
was used in deep cavities with little surface area, it could take along
time for the cure to complete, and the acid could corrode some of the
parts. GE recommended another version of the RTV which had a different
curing agent and was not corrosive. Sorry, I don't remember the part number.

For most aircraft sealing applications the surface area is large in comparison
to the thickness. Also acetic acid is relative weak, and I don't remember
enough chemistry to predict how it reacts with aluminum. My feeling is
that the copper wires we were worrying about then turned green much faster
than aluminum would be attacked. The worst case would be where the RTV
was sandwiched between parts in a thick layer, like as a bedding material
between a windshield and the fuselage. My Swift has had a lot of corrosion
over the years, but none which I could attribute to RTV. GE should have
material data sheets that would answer the question. -- Jack

Am changing the side windows and doing away with the frames. Do you know
what folks use mounted to the top of the glass to pull the windows up

have better ideas. Maybe there is a fresh extrusion someplace that would
make a good replacement? Would appreciate any help you could give. Doc
Moore

Doc,
The pre-1948 Swifts had side windows like you describe. Bend up a piece
of aluminum to approximate the angles of your present frames. I think
the factory used .025 but .032 or even ..020 will work. Just a simple
right angle will work but if you want to be more elaborate copy the bends
of your present frames. It is not an extrusion, just bent in a bending
brake. The angles can be attached with 6/32 screws or rivets. I have even
seen the angles made out of plexiglass and glued or otherwise bonded to
the window plexiglass. -- Jim
